| Abstract: Al13 was formed by electrolysis method, using AlCl3 as raw material, Pt as electrodes. The effects of electrolyte temperature and the exchange frequency of the anode and the cathode on the synthesis speed of Al13, the ratio of Al13 in total Al and the electrolysis time needed were studied. The results show that, at the beginning of the electrolysis, the synthesis speed of Al13 and the ratio of Al13 in total Al increase as the electrolyte temperature rises, but decrease later; proper exchanging frequency of the electrodes could remove the passivation of the electrodes led by the aggradation of Al13 on the surface of the anode, thus, enhanced the synthesis speed of Al13 and the ratio of Al13 in total Al, reduced the electrolysis time needed. Under the optimal conditions, the liquid product of high quality with basicity of 82.1% and Al13 polymer accounted for 92.6% of total Al was successfully prepare. |
